5 Powerful BIS Certification Process for Rotary Electrical Machines
Here are some steps or outlines on how such manufacturers can be certified:
1. Identify the Applicable BIS Standard
Such manufacturers have to ascertain that the IS standard is relevant to the rotary electrical machines employed. Some of the common standards include:
- IS 4722: Specification for rotating electrical machines.
- IS 325: Specification for three-phase induction motors.
- IS 13364: Specification for alternators used for power generation.
- IS 9000: Environmental testing requirements for electrical equipment.
2. Application
Application submission is done using the BIS online portal and must include other relevant documents such as:
- Details of the manufacturing unit
- Specifications and test reports/reference documents for the product
- Factory layout with process flow
- Quality control measures adopted
- Calibrated certificates of testing equipment
- Details of safety and environmental compliance.
3. Product Testing at a BIS-recognized Laboratory
The test at a BIS-accredited lab shall be mandatory for all products in the course of which their adherence to safety, efficiency, and performance standards should be verified.
4. Factory Inspection
On-site inspection of the manufacturing facility by BIS officials for quality control procedures implemented, testing equipment available, and production capabilities.
5. Grant BIS Certification
Certification will be granted by BIS after fulfilling all the aspects making it possible for manufacturers to stamp ISI on Rotary Electrical Machines.
Documents Required for BIS Certification
To facilitate the certification process, the manufacturers are expected to furnish the requisite documents:
- Business registration certificate
- Plant details
- Test reports from BIS-approved testing laboratories
- Quality control documents
- Authorized Indian Representative (AIR) details in the case of foreign manufacturers
- Bill of materials (BOM) and drawings of the product
- Energy-performance compliance reports, wherever applicable
Cost of BIS Certification
BIS certification costs can vary based on the type of rotary electrical machine, the testing it requires, and the applicable BIS scheme. The main cost components include:
- Application fees
- Testing charges
- Inspection fees
- License fee upon approval
- Renewal and maintenance fees
Why BIS Certification is Required
Under BIS Scheme X, certain rotary machines must meet Indian Standards (IS) to ensure:
- Product safety.
- Performance efficiency.
- Environmental compliance.
- Quality assurance for domestic and export use.
Uncertified products may be banned from sale or rejected by regulatory bodies and government tenders.
Why BIS Certification is Required
BIS (Bureau of Indian Standards) is the national authority that sets product standards in India. Certification under Scheme X ensures products are:
- Technically compliant with Indian Standards
- Safe for public and industrial use
- Eligible for import, sale, and government tenders
- Traceable in case of manufacturing faults or failures
For rotary machines, failure to certify may lead to:
- Legal penalties under the BIS Act
- Product rejection at customs
- Ineligibility for B2B contracts or bulk sales
- Loss of credibility and brand trust
Types of Rotary Electrical Machines
Rotary electrical machines are devices that convert electrical energy into mechanical energy and vice versa. They are mainly of three types:
- DC Machines – DC motors and DC generators.
- AC Machines – Alternators, Induction motors, and Synchronous motors.
- Special Purpose Machines – Stepper motors, Servo motors, BLDC, PMSM, and Universal motors.
For safety, quality, and performance, manufacturers need BIS Certification for Rotary Electrical Machines. The Bureau of Indian Standards (BIS) regulates this, and products not under mandatory certification can obtain approval through BIS Scheme X certification.
Step-by-Step BIS Scheme X Certification Process
Step 1: Identify Product Standard (IS Code)
Determine the exact IS (Indian Standard) applicable to your machine model:
- Voltage rating
- Type (AC/DC/Universal)
- Use case (consumer, industrial)
Step 2: Register on Manakonline Portal
